Hi All,
I am moving a staircase and it will be parallel with the joists. As the house is 200 yrs old (not listed), the hole for the stairs actually fits between the joists (85cms wide). Building regs have asked for dimensions of trimmers and headers but I don't understand using these as I have not had to cut joists. Do I need to add a joist, cut it, and then apply headers and trimmers? I am guessing it will need strengthening somehow?
